The Met Office added “substantial changes in working practices and daily routines will be required”.

The national weather service also warns there is a “high risk of failure of heat-sensitive systems and equipment, potentially leading to localised loss of power and essential services, such as water or mobile phone services”.

There will also be more “significantly more people visiting coastal areas, lakes and rivers, leading to an increased risk of water safety incidents”.

The public has also been warned to expect delays on roads, along with delays and cancellations to rail and air travel.
